This article explores the best routines, how to load them, and how to use them to calculate total area efficiently. 1. What is an AutoCAD LISP Total Area Routine?
The Lisp function will calculate the total area of all selected objects and print the result to the command line.
Once loaded, you run the routine by typing its specific command name into the command line. For example, using the areacal.lsp routine, you would type AREACAL and press .
Shows the cumulative area only if you select objects of the exact same type (e.g., only polylines). If your selection includes a mix of polylines, circles, and hatches, the cumulative area field disappears. total area autocad lisp
If you aren't ready to write your own code, there are powerful pre-made tools available: TotalLength + / TotalArea : This popular plugin from the Autodesk App Store
Here is a basic snippet demonstrating how this works in Visual LISP (VLISP):
Copy the code below into Notepad and save it as TOTALAREA.LSP . This article explores the best routines, how to
You can copy and paste this code into the Visual LISP Editor (type VLISP in AutoCAD) to create your own "Total Area" command:
Once you've mastered the basics, you can tackle more complex area summation tasks, such as calculating hatch areas or performing a full project quantity takeoff.
If you work in architecture, civil engineering, or interior design, you know the drill: you receive a complex floor plan, a site layout, or a zoning exhibit, and your client asks, "What is the total square footage?" Not the area of one room, not the zoning lot—the grand total. In native AutoCAD, calculating multiple areas and summing them manually is a tedious, error-prone process. You can use the AREA command with the "Add" option, but it is clunky. You can create hatches and check their properties, but that takes too long. The Lisp function will calculate the total area
Right-click inside the text editor pane and choose . Under Field Category, select Objects .
Assumes your drawing units are in feet. Change the conversion multipliers if you work in meters or millimeters.
Whether you choose to download a ready-made tool, create a simple script of your own, or build a comprehensive QTO engine, the ability to quickly and accurately calculate the total area of selected objects will elevate your work, reduce errors, and free up your time for the creative and critical aspects of your projects. The power of AutoLISP puts this efficiency at your fingertips.
Here is a basic Lisp routine to do this:
Mastering "total area autocad lisp" is about recognizing that automation is not just a convenience, but a necessity for modern CAD productivity. Here is a quick guide to help you choose the right approach for your needs:
